CA 2638936

A module for testing and draining fire protection sprinkler systems is disclosed. The module has a chamber with an inlet duct in fluid communication with the sprinkler system and an outlet duct. A valve controls fluid flow through the chamber. A plate, having an orifice, is mounted within the chamber and is pivotable to a first or test position wherein the orifice is aligned with the outlet. Flow of water through the chamber is restricted by the orifice to simulate flow through a single open sprinkler head. The plate is pivotable to a second or drain position out of alignment with the outlet, allowing unrestricted flow. The module may include a pipe segment on which the module is mounted, the segment being integrated with a riser of the sprinkler system.
